What is the correct effect on the body of abnormally slow
respirations?
A. Decreased bicarbonate ion
B. Increased carbonic acid
C. Decreased carbonic acid
Increase bicarbonate ion .....ANSWER.....B. Increased carbonic
acid
When respirations slow, the body is not able to exhale the acid
in gases, carbonic acid will increase
,Page 2 of 65
Place the following events in the correct sequences of events
when ketoacids increase in the blood of a diabetic patient. Not
all options are used in the answers.
1. Serum pH decreases
2. Serum bicarbonate decreases
3. PCO2 decreases
4. Respiration decreases
5. Respirations increases
6. Serum pH increases
7. Urine pH increases
.....ANSWER.....2,1,5,3,7,6
As acids build up in the body, the serum bicarbonate decreases
in ratio to acid which lowers the pH (lower pH= higher acid
content). The body will then increase the respiratory rate in
attempt to compensate by exhaling acid during expiration to
,Page 3 of 65
decrease PCO2, the urine excretion of acidic components will
increase thereby increasing the serum pH (move it from acidic to
alkaloid to get the pH back to normal)
Serum potassium levels are affected by which of the following
1. ADH
2. Aldosterone
3. Serum H+ levels
4. Insulin levels
.....ANSWER.....2,3,4
Potassium levels are influenced by foods high in potassium such
as bananas, citrus foods, tomatoes, and lentils. Potassium levels
are also affected by the hormone insulin which promotes its
movement into the cells. Acidotic states shift potassium out of the
cell and into the extracellular compartments while alkalosis move
potassium into the cells

Which statements apply to atrial natriuetric peptide
1. It is secreted by heart muscle cells
2. It is a hormone secreted by the kidneys
3. It helps to control water and sodium balance
4. It is released in response to low blood pressure
.....ANSWER.....1,3
Atrial natriuretic peptide as you can infer from its name is
secreted by the cardiac cells and play a role in water and
sodium balance. ANP is a high pressure hormone meaning that it
is not released during hypotension or low circulating volume. The
opposite is true. It is released when the atrium is stretched as a
heart failure
What are the three mechanism that control pr compensate for
serum pH .....ANSWER.....Buffer pairs in blood, change in kidney
excretion rate, change in respiratory rate
